Most of the time a client will feel relaxed and uplifted by a Reiki treatment. However, sometimes a client will have what is called a "healing crisis". As a person’s vibration goes up, toxins that have been stored in the body will be released into the blood stream to be filtered by the liver and kidneys and removed from the system. When this happens, sometimes a person can get a headache or stomach cramps or feel dizzy, nauseous or weak. If this happens, it is a good idea to drink more water, eat lighter meals and get more rest. The body is cleansing as part of the healing process, so this is a good sign.
